Objective: To investigate the relationship of nm23 and VEGF expression with hilar lymph node micrometastasis and the prognosis of stage Ⅰ non-small cell lung cancer (NSCLC). Methods: Immunohisto-chemistry was used to detect nm23 and VEGF protein expression in primary cancer tissue and cytokeratins in 86 hilar lymph nodes from 40 patients with stage Ⅰ NSCLC. Kaplan-meier method and Log rank test were used to analyze the 5-year survival. Results: The rate of positive hilar lymph node micrometastasis was 12.5% for stage Ⅰ NSCLC. Lymph node micrometastasis was not statistically correlated with gender, age, histologic type, differentiation, primary tumor size or VEGF protein expression (P>0.05). But it was reversely associated with nm23 protein expression in primary cancer tissue of NSCLC (P<0.05). The 5-year overall survival of pa-tients with well-differentiated NSCLC, positive nm23 expression and negative lymph node micrometastasis was better than those with moderately and poorly differentiated NSCLC, negative nm23 expression and posi-tive lymph node micrometastasis (P<0.05). Lymph node micrometastasis and nm23 protein expression were identified as two independent prognostic factors for stage Ⅰ NSCLC by univariate Cox regression analysis.Conclusion: nm23 protein expression in pdmary cancer tissue of stage Ⅰ NSCLC is closely associated with hi-lar lymph node micrometastasis, nm23 protein and hilar lymph node micrometastasis are two independent prognostic factors for stage Ⅰ NSCLC. Patients with nm23 protein deletion and positive lymph node microme-tastasis have a poor prognosis.

Objective To investigate the influence of injection color regents concentration on completed resection rate, operation time and injection volume of patients with intestinal tumor by ESD.Methods 90 elderly patients with intestinal tumor by ESD were chosen from June 2013 to June 2016. They were randomly divided into 3 groups including A group (30 patients) with glycerin fructose used alone, B group (30 patients) with glycerin fructose combined with 2% mythylene blue on the basis of glycerin fructose and C group (30 patients) with glycerin fructose combined with 4% mythylene blue on the basis of glycerin fructose; and the completed resection rate of tumor, operation time, injection volume and complication incidence in the peri-operative period of 3 groups were compared.Results There was no signiifcant difference in the completed resection rate of tumor among the 3 groups (P < 0.05). The operation time and injection volume of C group were signiifcant better than A group and B group (P< 0.05). There was no signiifcant difference in operation time and injection volume between A group and B group (P < 0.05). There was no signiifcant difference in the complication incidence in the peri-operative period among the 3 groups (P < 0.05).Conclusion Compared with glycerin fructose used alone and glycerin fructose combined with 1% mythylene blue for 2 mg, glycerin fructose combined with 1% mythylene blue for 4 mg by intestinal submucosal injection on patients with intestinal tumor by ESD can efifciently shorten the operation time and reduce the injection volume.
